Be it known that I, EDMUND J. KENNEY, a citizen of the United Sta-tes, residing at Towson, in the county of Baltimore and State of Maryland, have invented new and useful Improvements in Roofing-Nails, of which the. following is a specification.

lThis invention relates to rooting nails of tor securing flexisuch as rooting felt,

ble .and brous roofing,

In order to hold tar paper and the like. rooting of this class tomary to vemploy roofing nails having washers ot sheet metal, or similar material adapted to engage the roofing material to provide a large bearing surface whereby the roofing. material will be held securely and I overlap the bridge piece, as shown at 3,

with little danger ot becoming detached or torn by the wind or by other causes.

The resent invention has for its object to provide a rooting nail whereby the separate washer may be dispensed withA and which shallv provide an extended bearing surface to engage the roofing material to prevent the latter from becoming detached.

A further object of the invention is to in the form of a clip or staple having two engaging pins, an intermediate extended bridge piece and engaging heads.

A still further object of this invention is to provide a rooting nail of the character dsc'ribed having a curved resilient bridge piece which, when the nail is applied to the rooting material, will press downward upon the latter between the points or prongs oi the nail, thereby retaining the rooting material securely in position.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and parstood that no limitation is necessarily made,

to the precise structural details therein eX- hibited, but that changes, alterations and modications within the scope of the claims may be resorted to when desired.

In t-lie drawing, Figure l is a plan view spective view showing a securely in position and vto prevent it from tearing, ithas been cuspreferred form ofv the invention, it being, however, under-l showing a portion of a roof tok whichroofingvmaterial secured by a simple and |preerred form of the improved roong nails has been applied. Fig. 2 is a side elevation of one of the nails. Fig. 3 is a top plan view of one of the nails. Fig. 4 is a erslightly modified form of the nail.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved nail may be simply and inexpensively-made of a pieceot' steel wire, and it includes a bridge piece 1 at ,the ends of which are formed horizontally dis osed eyes 2, 2, said eyes being formed by nding the wire or material of which the nail is formed, the ends being caused to cross or after which the terminals are bent downward at right angles to the -bridge piece and the eyes so as to be provided with sharp driving edges, as shown at 5. The bridge piece 1 which with respect to the prongs 4 is of relatively great length is curved or disposed downwardly intermediate the eyes or heads 2, 2, as clearly shown in Fig.` 2.

Instead of forming theI heads 2 inthe shape of eyes, as shown in Figs. 1 to 3, inclusive, the said heads may be formed by merely doubling the wire upon itself, as shown in Fig. 4, sofas to orm ahead eX- tension 6. In other respects the construction is as previously fdescribed.

When applying roofing material, shown at 7 iii Figa-1, each strip of said roofing material is secured by the improved nails adiicent to its lower edge, the said nails being suitably spaced, as shown, so that the shedding of water will not be obstructed thereby. As the two prongs of 'each nail are driven, the intermediate resilient arch or bridge piece will be straightened upon the roofing material, and the medial portion of such bridge piece will thus exert a down-v ward tension or pressure which is found very effective terial and preventing it from bulging between the prongs of the nail. It will also be seen that each nail is provided with heads form prongs 4 which may in retaining the roofing manail is composed, said heads being'likewise 110 effective in holding the roofing material 'ing the downturned prongs being .disposed cuz-ely in place; aoross the bridge ieee. y v 2o vIt is 'obvious vthat other forms ef heads z 2. A rooting nail formed of a single piece may be effectively used in connection witlh of wire' and comprising a bridge p leee,
